Abstract

Changes in day length regulate the proper timing of flowering in several plant species. The genetic architecture of this process is based on CCT-domain proteins, many of which interact with NF-Y subunits to regulate transcription of target genes. In the model plant . Arabidopsis thaliana, the CONSTANS CCT-domain protein is a central photoperiodic sensor. We will discuss how the diurnal rhythms of its transcription and protein accumulation are generated, and how the protein engages into multiple complexes to control production of a systemic flowering signal. Regulatory parallels will be drawn between . Arabidopsis and major crops that indicate conservation of some CCT/NF-Y modules during plant evolution. This article is part of a Special Issue entitled: Nuclear Factor Y in Development and Disease, edited by Prof. Roberto Mantovani.
